Alpha-particle emission from the reaction 1354 MeVHo165+Ta181

The emission of $\alpha$ particles from the deep-inelastic reaction 1354 MeV ${}_{}{}^{165}{}_{}{}^{}\mathrm{Ho}$ + ${}_{}{}^{181}{}_{}{}^{}\mathrm{Ta}$ has been studied. Alpha particles were detected in coincidence with a projectilelike fragment, both in and out of the reaction plane. Average velocity diagrams, $\alpha$-particle energy spectra as a function of angle, and $\alpha$-particle angular distributions are presented. The in-plane data show that the bulk of the $\alpha$ particles in coincidence with the deep-inelastic exit channel can be explained by evaporation from the fully accelerated fragments. The out-of-plane $\alpha$-particle angular distribution data together with gamma-ray multiplicity data from previous work give a consistent picture of the transfer and partitioning of angular momentum between the two fragments.
